Bad motor mounts allow the engine to move forward under hard braking.
BMW put a limiter in place that attaches to the bottom of the bellhousing and hits the subframe to prevent this from happening when the engine mounts fail, but the rubber damper on the limiter is typically missing, allowing the fan to ruin the radiator.
